Just a status update.  Richard has implemented enough of this that I've
been able to run some performance tests, and this changes it this pybench
test from being 57% slower than 2.4.3 to being 32% faster.  Go Richard.
It's looking pretty good so far.

Now we just have to keep it from exploding.

Thanks,
Sean
